Im on PopOS and I had one boot problem where I had to pop in a ubuntu flash drive to run boot repair on, but that was like 3 years ago. There are definitely issues that come up sometimes when I upgrade to a new kernel version but it mundane stuff like my printer wont scan duplex. But now AI just helps me fix that stuff I don't spend too much time on it.
I wrote an article on my transition [0]
